More recently, interferometers such as the Atacama Large
Millimeter/submillimeter Array (ALMA) have overcome the dust bias,
with the detection of \(\sim \)  10 molecular gas-rich systems using CO
rotational transitions and the atomic [CII] line
[1]}, [2]}, [3]}, [4]}.
So far, these studies have focused on tracing relatively
high-metallicity systems, finding the DLA hosts at relatively
large impact parameters, \(\sim 16 - 45 \rm \ kpc\) , and with high
molecular gas masses of \(10^{10}-10^{11} M_{\odot }\) . Following these successes,
efforts to detect more representative DLAs are ongoing.
